Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Repair Windows errors before they cause bigger problemsFix Now →You can get a rechargeable electric toothbrush with useful brushing feedback for well under $100. Oral-B’s U.S. site listed the iO Series 2 at $44.99 and the Pro 500 at $39.99 when checked for this article—but those are manufacturer-site prices, not verified Amazon Prime Day deals. Check the live listing before you buy; the “spying on your molars” line is a joke, not a verified claim about a particular $500 brush or its privacy practices.
Are these actually Prime Day deals?
That is not established by the available price information. Oral-B’s product pages showed the prices below, but they do not confirm Amazon pricing, a Prime membership requirement, a discount from a prior price, or an active sale. A retailer listing can change, so check the exact model and price on Amazon before treating either brush as a deal.

Philips has also announced refreshed Sonicare ranges in 2026, but the available product information does not establish a specific Sonicare model’s current price or features under $100. The comparisons here therefore focus on the two Oral-B models with substantiated U.S. product-page details.

What to weigh before choosing
Upfront price and refill cost
The handle is only part of the cost. The iO Series 2 includes one refill head, and its replacement heads are a separate, compatibility-specific purchase. Check the cost and availability of the right refills before deciding that a lower checkout price makes it the less expensive option over time.

Head compatibility
Oral-B says iO Series 2 handles fit iO heads; legacy Oral-B heads do not fit iO handles. If you already own Oral-B refills, confirm the handle family before buying this brush or ordering replacement heads.
Feedback and simplicity
The iO Series 2 has a pressure sensor, three modes, and timed quadrant alerts according to Oral-B’s U.S. product page. These are practical features for shoppers who want cues while brushing. The Pro 500 is a simpler, lower-cost alternative in the available information, but the Pro Series page does not provide enough detail here to claim a precise feature difference beyond what is documented.

Charging and travel
The iO Series 2 kit includes a magnetic charger. Philips One HY1100/02 is a battery-powered option, but the available product details do not support a direct comparison of battery life, charger convenience, or brushing performance.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsHow to verify an Amazon offer
- Search for the exact model name, not just “Oral-B electric toothbrush,” and confirm the listing identifies the iO Series 2 starter kit or Pro 500.
- Check the price shown at checkout and whether the offer requires Prime membership. Compare it with the manufacturer-site prices cited above, not an unverified struck-through reference price.
- Confirm the sale end date and availability on the listing. A product’s presence on a deals page or in older buying coverage does not establish a live promotion.
- For the iO Series 2, verify that the kit includes the items you expect and budget for iO-compatible replacement heads.
What the “smart” label does—and does not—tell you
“Smart toothbrush” is not enough information to judge privacy. The available product details establish the iO Series 2’s brushing modes, sensor, timer, charger, and included head; they do not document a specific $500 brush or establish what data any connected model collects. If app connectivity is part of a model you are considering, review that product’s privacy information directly rather than assuming either that it spies on you or that it collects nothing.
